BOILER FOR USE IN OIL FIRING 2 Filed oct. 2o, 19:55

The object of my invention is to provide a n boiler which will result in efcient and economical operation with oil firing.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawing in which- Fig. 1 is a side elevation of a sectional boiler constructed in accordance with my invention.

Fig. 2 is a transverse sectional elevation taken on the line 2-2 of Fig. 1. v

Fig. 3 is a longitudinal 'sectional elevation taken on the line 3 3 of Fig. 2.

Each of the water sections 5-11, inclusive, is provided with a lower kbaie 19, and each of the sections 6-12, inclusive, is Aprovided with an upper baie 20. In the assembled boiler as shown in Figure 3, the lower baffles 19 form a horizontal baffle Wall 21 extending from the front of the boiler to a point a short distance from the back of the boiler, and the baflies 20 form a baiile wall between the baile wall 21 and the top of the boiler extending from the rear of the boiler to a point a short distance from the front of the boiler. Hence, the combustion gases rising from the combustion chamber 16 pass rearward under the baiiie wall 21, around the free end of the latter and then forward between the baffle walls 21 and 22, and finally rearward again between the top of the boiler and the baie wall 22,

thence out through the flue. As a result, a maximum absorption of heat in all of the watercarrying parts of the boiler during passage of the hot combustion gases, is obtained.

Referring to Figures 1, 2, 3,-4 represents a steam or hot water heating boiler which includes a plurality of sections 5, 6, 7,8, 9, 10, 11, 12. The sections are adapted to contain water, and their bottoms are connected by nipples 13 whereby the interior of all the sections are in communication and water can flow from one section to the other through the passageways provided by said nipples. Nipples 14 provide communication between the upper spaces of the sections. The steam or hot water is distributed by outlets 15. Sections 5, 6, 7, and 8 extend to floor and provide for forming combustion chamber 16, thus surrounding the front, rear, sides 'jand bottom of combustion chamber 16 with water. Sections 9, 10, 11, 12 are similar to sections 5, 6, 7, 8 in design, except they do not extend to floor, but instead extend to and are supported by base 18, thus forming a travel for the gases of combustion and also providing additional heat absorbing surfaces 17.

The common type of oil burning boiler has the base extending from the front section tothe rear section. A combustion chamber is provided by lining the front, sides, and to a distance of the required length and depth, the base and portion of the heating surfaces with fire brick or other re protecting material. 'Ihe'result is that since there is no water around the combustion chamber, the high temperature therein results in a high radiation loss through the base. Further,

' all heat absorbing surfacesback of, and below the top of rear wall of combustion chamber becomes useless in its function of absorbing heat,

in that the gases of combustion will fail to come in contact with ythese surfaces. Further, in

common types of boilers it is practically impos-` sible to prevent inltration of air between the base and floor, andalso between the base and sections.

The object of my invention is to overcomethe above described faults. Referring to Figs. 2 and 3,-16 is the combustion chamber, formed by sections 5, 6, 7, and 8, and is lined with fire brick or otherfire protecting material. The heat vof' combustion absorbed by the nre brick or other lining protecting sides and floor of combustion chamber, Will be absorbed by the water surrounding the combustion chamber. Since this water is in communication with the other water in the boiler it will result in increased efficiency and also result in reduction o f radiation losses around the combustion chamber. Further, the gases of combustionI in'travelingjthrough the boiler to the chimney will of necessity have tol come in 'contact with -surface 17, which I have provided as additional heat absorbing surface. Further, by my assembly of sectionsA as shown in Figs. 41 and 3, the only air to enter theboiler will be that blown in by oil burner blower, thus eliminating all infiltration losses. Tov provide for conditions 'wherebyv the length of combustion chamber 16 varies it is proposed to add additional sections 6 and 7, such. that the combination of sections 5 to 8 inclusive will give required length to 16;

Having thus described my invention, what I s PAT'NT oFFIiCEf* claim as new and desire to secure by Letters l the rearward sections extending from the top of the boiler to a level above the floor, each of said sections with the exception of the rearmost having a hollow Water-carrying baille located at a distance from the top of the boiler, said watercarrying bafes being horizontally aligned to form a; baille Wall'extending from the front of the boiler to a point near the back of the boiler, each of said sections with the exception of the 10 forwardrnpst having a hollow water-carrying bam@ located between sala mst-namedbame and the top ofthe boiler, said last-named bailles being horizontally aligned to form a baille wall extending from the rear of the boiler to al point near the front of the boiler, the boilerflue being located at the rear of the gas compartment formed between the top offthe boiler and said last-named baffle Wall.
